Title: Laser beam position sensing system for high power laser
Inventor: CHEN SHIANG-LIANG
IPC: B23K26/02
Filed: 1996-04-02
Granted: 1999-08-01
Abstract: A new device for in-process beam position sensing required for the control of quality in high power CO2 laser materials processing has been presented in this study. The system uses a beam-splitter to reflect a small part of the beam energy into a position sensing unit. The devices consists of a beam-splitter, rotating slit, focusing lens and photosensor. The signal is dependent on the beam power beam radius, beam location and the width of the slit. The device can be used to analyse the beam energy center within a duration of 2 sec. The absolute beam location can be found if the beam diameter is known. The beam power can be estimated by integrating the energy signal from each angle of rotation.

Granted: 2000-12-01
Abstract: The present invention provides an apparatus for detecting the deviation of stopping position of a moving body, on a floor surface where an arbitrary pattern is formed, which can correct position of a moving body with high precision while preventing the influence of disturbances. The apparatus of this invention comprises the following. A moving operation position data acquisition device that can stop a moving body, that moves on a floor surface such as a punching floor where arbitrary patterns and specific recognition marks are formed, at a specified position, and pick up an image of the floor surface at that position to obtain a moving operation image for acquiring and constructing relevant position data of plural posture portions and recognition marks of an arbitrary pattern. A reference position data acquisition device that can stop the moving body at a specified reference stop position in advance and pick up an floor surface image at that position to obtain a reference image for acquiring the position data on the reference image relevant to the posture portions and recognition marks. A symbol attaching device that attaches the plural posture portions onto the images with the recognition marks as reference common symbols. A matching device for 1-to-1 matching the images and posture portions based on the symbols. A deviation computing device that can calculate deviations in position data for the matched posture portions and obtain deviations between images according to the position data deviation of each group. Deviations in the position and posture are obtained by using many pieces of position data to enable high-precision measurement, and even when part of it can not be recognized under the influence of disturbing light, the processing can be performed without any problem. Moreover, because the position data of each individual posture portion are used, the measurement position will not be affected even if the posture position has manufacturing errors.

A conducting layer that includes a protuberant structure with trapezoid cross section is formed. A spacer is formed on the side edge of protuberant structure. The plasma gas stated above is used to perform the dry etching process onto part of conducting layer by using the spacer as a mask and insulating layer as stop layer so as to form bottom a electrode, which includes a horn, located on the node contact window and part of insulating layer. After that, the spacer is removed and, on the bottom electrode, a dielectric layer and an upper electrode are sequentially formed.
